THOMAS D. XVORRALL, OF WASHINGTON, DISTRICT OF COLUMBIA.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,750, dated July 19,1887.

Application filed November 5, 1885. Serial No. 181,915. (No model.)

To all whom, it may concern:

Be it known that I, THOMAS D. \VORRALL, a citizen ofthe United States,residing at \Vashington, in the District of Columbia, have inventedcertain new and useful Improvements in Type-Writing Machines, of whichthe following is a specification, reference being bad therein to theaccompanying drawings.

My invention relates to improvements in type-writing machines, andespecially to that class of machines in which fonts or batteries of typeare arranged in a moving frame, as described and claimed in my PatentNo. $3 1,503, of January 19, 1886.

Figure 1 is a top or plan View of my ma chine. Fig. 2 is a side view ofthe same, partly in section, taken on the line :0 a: of Fig 1. Fig. 8 isan end view of the type-carrying frame. Fig. tis a detached view of thecentering-bar and a portion of the type-carrying frame. Fig. 5 is a sideview of one of the adjustable arms for regulating the spacing of theletters. Fig. 6 is a side view of a portion of the bottom of the mainframe, showing the lower rod of the transverse frame passingtherethrough.

Referring to the drawings, A is a rectangular frame, on the corners ofwhich are secured the posts or brackets B, in which the rods or bars 0and D are secured.

E is the type-carrying frame, the rear end of which is adapted to slideback and forthon the rod D to bring the proper letter to the printingpoint or center.

F is the type-carrying drum or cylinder, 111 which the type are arrangedin rows in the periphery thereof. The type drum or cyl1nder is mountedin suitable hearings in the frame E, so that it can be readily turned tobring the proper row of type in posltion to opcrate on the paper, saidtype-drum being provided with notches or recesses a at one end toreceive the sliding bolt G, which is secured to the frame E, so thatwhen the type cylinder is turned to bring the desired row of typeintoprinting position it can be locked and securely held in such position.The front end of the type-carrying frame is provided withknobs orhandles H, by means of which the frame can be readily moved back andforth on the rod 1). I

form the letter or character, it being under- 'stood that the notches inthe bar I are marked with the same letters or characters as 0011- tainedin the printing line of type in the cyl- The setscrews care for thepurpose of holding the sleeve 1) on the bar 0, so that said sleeve canbe accurately adjusted to bring the printingcenter directly on the topand center of the paper-drum.

L are bars or brackets adjustably secured to the rear end of thetype-frame by means of thumb-screws, said brackets being connectedtogether by a bar, M, which impinges on the pawl-operating mechanism tooperate the same, as will more fully hereinafter appear.

N is a frame mounted transversely to the frame A, and connected theretoby means of the rod a, which passes through the sides of the frame. Theframe Nconsists of the end pieces, O and I, and the connecting-rods (Z.

R is a rod mounted in bearings d, and ren dered adjustable by means ofscrews 0 in the ends 0 P, and on which is mounted the paperholdingcylinder S, the heads of said cylinder being provided with aperturesthrough which the rod R is passed. The rod It is provided with aleft-hand screw-thread, 0, into which a bolt, f, secured on the end ofthe cylinder, is forced by the spring f, which causes the cylinder S tomove rearward as it is turned by the pawl-plate, and when it is desiredto move the paper-cylinder forward for the purpose of putting on a newsheet of paper the springbolt is raised and the paper-cylinder drawnforward. The paper cylinder is provided with a slot, T, in which theends of the paper are secured by means of a beveled strip fitting insaid slot over the paper in the usual man ner.

U is a ratchet-disk secured to the rear end of the paper-cylinder S,which is engaged by the pawl plate V to turn the paper-cylinder theproper distance to space between the letters; The teeth of a portion ofthe ratchetdisk U opposite the end of the slot T are cut away, as shownatg,Fig. 2, so that when the paper-cylinder has reached that point inits revolution and the end of the line of printing has been reached thepawl-plate will drop into the recess causing the pawl-plat'c to strikethe hammer i and ring the bell k to warn the operator that the end ofthe line of printing has been reached. WVhen the pawl-plate drops intothe recess 9, it ceases to act on the papercylinder until said cylinderis moved over the slot to commence a new line of printing,which is doneby turning the cylinder so as to bring the pawl-plate into cont-act withthe ratchet teeth of the disk again,

The pawl-plate V is made of the same length as the paper-cylinder, sothat it will operate at all times on the ratchet-teeth of the disk U, nomatter in what position the papencylinder is on the rod R. v

The pawl-plateVis pivoted upon arodflV, connecting the two side arms ofthe pivoted frame XV, said frame being pivoted upon one of the rods cland held in normal position by the spring 7:, attached at one end to thebed-frame, and at the other to a stay-rod,W of the frame XV. At is shownan aperture for another stay-rod, and the upper ends of the side piecesof the frame WV are connected by still another rod, Z, which liesimmediately beneath the bar M of the type-carrying frame, so that whenthe front of said frame is lifted the bar I is pressed down, rockingtheframeW against the stress of spring 71 and causing the pawlplate topositively turn the paper-cylinder. \Vhen the bar M rises, frame \rVisrocked up ward by its spring h and the pawl-plate drops back one or moreteeth of the ratchet-wheel.

As before stated, the bars L, which support the crossbar M, are madeadjustable on the type-carrying frame, so that said bar M can be movedtoward or from the typecarrying frame, and in this manner adjust thethrow of the swinging frame carrying the pawl-plate to regulate ordetermine the spacing. It will be seen that if the bar M be movedfarther from the pivotal point of the type-carrying frame the swingingframe \V will be forced down farther by the upward movement of the frontend of the type-carrying frame than if the bar M were nearer to thepivotal point of the type-frame, and thus move the paper-cylinder aroundto space the distance between the large letters. Vhen spacing for smallletters, the bar M is moved forward toward the bar D, or pivotal pointof the type-carrying frame.

As a further means of limiting the movement of the swinging frame WV,and the consequent movement of the pawl-plate over the ratchet teeth ofthe disk U, I pivot one end of the bar A to the top of the end I of thetransverse frame N, the other end of said bar being provided with aslot, m, through which the barl of the swinging frame W passes. The

- sesfiso bar A is provided with a series of holes, a,

1 which pass through the slot n, said holes bethrow of the type-carryingframe "to space the distance between the letters, I join the front endof the type-carrying frameto the sliding standard B by means of asliding connection, which consists of a T-headed projection or hook, r,passing through a slot in said standard, which will allow the front endof, the typecarryin g frame to be raised and lowered,

the throw of said frame being limited by the i The lower end of thestandadjustable pin ard B is provided with a hole, which adapts it toslide back and forth wit-h the type-frame on the rod 0.

D. are troughs or strips, of wood or suitable material, secured at oneend to suitable supports on each side of the paper drum, while the outerends of said troughs are secured to the ends of the rectangular frame A.

The bars D are designed to support the inking ribbons or pad E, so thatwhen the type-drumismoved back and forth in the processes of writing thetype will be supplied at all times with a suitable amount of ink, andwhen fresh surfaces of the inking-ribbon are required it may be movedforward by winding or unwinding from the drums or spools F. i.

Having thus described my invention, what I claim, and, desire to secureby Letters Patent,

1. In combination with the traveling paper cylinder and itsratchet-wheel, the elongated pawl-plate V, constructed and arranged, asdescribed, to operate on the paper cylinder throughout its travel.

2. In a type-writing machine, the pawlplate V, constructed as described,mounted in the swinging and spring-held frame W, in combination with thetype-carrying frame E, provided with the adjustable bar M, and thepaper-cylinder having the ratchetdisk U, as set forth.

3. In a type-writing machine, the pawl-carrying frame W, in combinationwith the slotted bar A, having the holes a and set-screw v, as and forthe purpose set forth.

4. In a type-writing machine, the paper drum or cylinder S, having theratchet-disk ICC U, provided with the recess 9, in combination andrecesses corresponding to the rows, and the sliding bolt mounted on theframe as set forth.

6. The combination, with the type-cylinder and its pivoted frame, havingthe notched bar K, of the adjustable guide-bloek Z), as set forth.

7. The combination, with the pivoted typeearrier having adjustable armsL and bar M, of the paper-roller, its ratchet-Wheel, and the elongatedpawl-plate, as set forth.

8. The combination of the sliding frame, the type-cylinder journaled insaid frame and having longitudinal rows or alphabets of type andrecesses corresponding to the rows, and 15 the sliding bolt mounted onone of the side bars of the frame, as set forth.

9. The eombinati0n,with the paper-roller and its ratchet-wheel, of theelongated pawlplate, the pivoted type-carrier, and the bar M, 20 mountedon adjustable arms L, as set forth.
